IMPROVEMENT IN EXTENSION-TABLES.

Specification forming part of Letters Patent No. 152,257, dated June 23, 1571; application filed April 10, 1874.

To all whom it may concern:

Be it known that we, OLNEY S. THAYER, of Bellingham, and WILLIAM H. BRITToN, of Milford, of the State of Massachusetts, have invented a new and useful Improvement in Extension-Tables; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawings, of which- Figure 1 is an under-side view, and Fig. 2 a longitudinal section, of an extension-table Fig. 3 is a top view of the extension sector or leaf P, to be hereinafter described. Fig. 4 is atop view of the table with the extension-sector l? in place' therein.

Our invention particularly relates to the mechanism for connecting the two extension wings or halves of the table.

In the drawings, A B denote the said wings or extension-halves, each being provided with two legs,a a., and, if required, with a leaf, b, hinged so as to be capable of being turned from a vertical position up into a horizontal one, and there held by a brace or arm, c, duly hinged to one of the leg connections d d. From each leg a there is projected inward and underneath the part of the table-top which rests on such leg an arm, c, and between each pair of such arms in range with each other there are disposed, as shown, two bars, G C', parallel to each other, and to the two pairs of arms. A bar, D, having projecting from its middle, as shown, a leg, E, goes and slides freely horizontallyY through the bars O C' at their middles, and at each end is furnished with a head, f. Each of the bars C C' isconnected with the next adjacent pair of arms e e by two bars or pieces, G G' arranged as shown, such pieces G G', being connected to their bar C or O', and to the next two arms c c, by hinges, arranged as shown at g g and h hi When the table is extended so that the two portions of its top are parallel, each pair of arms c e, the next adjacent bar C or C', and their connection-bars G G', will be brought into line or range with each other, as shown in Fig. 5, which exhibits an under-side view of the table as` extended.

In order to facilitate the separation or moving apart of thc two bars C C', while the table may be in the act of being closed, we ap ply to each leg-bar el a wedge or cam, H, to project therefrom in manner. as shown. These cams or wedges, by entering between the bars O O, press them asunder.

The central leg and its support-bar may sometimes be dispensed with, but generally they will be necessary to the production of a strong table.

Instead of leaves with parallel edges, our table admits of the use of one or more leaves of a sectoral form, or whose opposite edges incline to or diverge from each other, a leaf of such description being shown in top View at l?, in Figs. 3 and 4.

We claiml. The combination of the slide bar D with the central leg E, the two bars C O', the four arms c c c c, and the vconnection-bars G G' G G', hinged together and arranged with the two halves A B of the table, as specified.

2. The combination of the cams or wedges H H with the two wings or table halves A B, and the bars C C', the four arms c c c c, and the connection-bars G G' G G', all being arranged and applied as set forth.
